Key benefits Precise and repeatable crack evaluation: a clear grid laid out on quality acrylic provides accurate markings that support detailed crack measurements with consistent results. Simple, reliable monitoring: tracks horizontal and vertical movement with dependable performance and requires no digital tools or complex setup. Flexible and accurate tracking: two removable pins offer versatile placement, while a cursor on the chart system shows movement for easy recording and analysis. Clear change measurement over time: manual 2D monitoring measures crack changes over time, delivering consistent analysis and dependable progress tracking. What it is and how it helps Material and design: built on a quality acrylic grid for clear visibility and precise readings, enabling straightforward crack evaluation on walls and surfaces. Function and performance: a manual, 2D monitoring method that provides consistent observations without digital complexity, suitable for ongoing monitoring and documentation. Compatibility and use: designed to be used on standard wall cracks in masonry or concrete surfaces, with a simple setup that supports reliable longterm tracking. Specifications and features Grid method: clear acrylic with precision markings for accurate crack readings. Movement tracking: records horizontal and vertical shifts in a straightforward, nondigital system. Movement indicators: two removable pins and a chartbased cursor to show and log movement clearly. Change measurement: manual 2D comparison to monitor changes over time for consistent analysis. 23 practical use scenarios Residential repairs and renovations: monitor development of cracks in plaster or masonry walls over the course of construction and after repairs to ensure stability. Construction QA and curing: track crack formation in concrete walls during curing and temperature cycles to verify structural performance. Heritage and sensitive structures: perform longterm crack monitoring with a nonelectronic tool to minimize disturbance while documenting progression. Why choose this device It provides a reliable, easytouse solution for accurate crack monitoring without the need for digital devices. The clarity acrylic grid enhances readability and reduces reader error. The combination of removable pins and a movement cursor enables flexible, repeatable measurements across multiple cracks and project phases.
